Everything you need to know about cost segregation studies
Cost segregation is an IRS-approved tax strategy that reclassifies building components into shorter depreciation lives (5, 7, or 15 years instead of 27.5 or 39 years). This accelerates your deductions and puts more cash back in your pocket sooner.
An engineering-based analysis breaks your property into individual components—electrical, plumbing, flooring, site work, etc.—and assigns each to the appropriate IRS asset class. The result is a detailed report your CPA uses to claim accelerated depreciation on your tax return.
Standard depreciation spreads deductions evenly over 27.5 years (residential) or 39 years (commercial). Cost segregation front-loads those deductions by identifying components that qualify for 5, 7, or 15-year recovery periods—giving you larger write-offs in the early years of ownership.
Yes. It is fully supported by the IRS and U.S. tax code. The IRS has published an Audit Techniques Guide specifically for cost segregation, and the strategy has been upheld in Tax Court rulings.
Bonus depreciation lets you immediately expense a percentage of qualifying short-life assets in the first year. When combined with cost segregation, it can generate substantial first-year deductions. The percentage phases down under current tax law, so timing matters.
These are IRS-defined asset classes. 5-year property includes items like appliances, carpeting, and certain electrical. 7-year property covers furniture and specialized fixtures. 15-year property includes land improvements like parking lots, landscaping, and sidewalks.
Items like appliances, cabinetry, decorative flooring, accent lighting, and specialized electrical systems. These are components that serve the business activity rather than the building structure itself.
Parking lots, landscaping, fencing, sidewalks, drainage systems, and exterior lighting. These typically qualify for 15-year depreciation and are eligible for bonus depreciation.
Nearly any income-producing or investment property qualifies, including:
We generally recommend cost segregation for properties valued above $300K–$500K, though the real threshold depends on your tax situation and available income to offset. We'll tell you upfront if the numbers don't make sense for your property.
Yes—and short-term rentals are often the strongest use case. If you materially participate in managing the property, the resulting depreciation can offset your active income without needing Real Estate Professional status.
Yes. Renovations and improvements can be separately analyzed and depreciated using shorter asset lives. This applies whether the renovation was done at purchase or years later.
Yes, if they own U.S. income-producing property subject to U.S. taxation. The same depreciation rules apply regardless of the investor's country of residence.
Real estate investors, developers, syndicators, hospitality operators, retail property owners, and commercial landlords see the greatest impact. Any business that owns or leases property with significant tenant improvements can benefit.
Ideally in the year you place the property in service—that maximizes the benefit window. But a study is valuable at any point during ownership. Properties held for years can still generate substantial catch-up deductions through a look-back study.
Yes. Using IRS Form 3115 (Change in Accounting Method), you can claim all previously missed accelerated depreciation in a single tax year. No amended returns required—the catch-up deduction flows through your current-year filing.
No. The study needs to be completed before you file your tax return for that year, not before year-end. This gives you additional time to engage a provider and gather documentation.
A look-back study is performed on a property you've owned for one or more years. It identifies depreciation you should have been claiming and lets you capture it all in the current tax year via IRS Form 3115—without amending prior returns.
Form 3115 is the IRS form used to request a change in accounting method. In the context of cost segregation, it allows you to switch from straight-line depreciation to accelerated depreciation and claim all missed deductions in one year.
No. The Form 3115 process captures all missed depreciation in your current-year return. This is one of the most powerful aspects of a look-back study—no paperwork headaches from prior years.
Yes. You can perform studies on new acquisitions, renovations, or previously unsegregated properties at any time. Many investors do studies across their entire portfolio.
Typically 20%–40% of a property's depreciable basis can be reclassified into shorter-life assets. The actual tax savings depend on your marginal rate, but most clients see 5x–20x return on the cost of the study.
Most studies deliver a return of 5x–20x the study cost through first-year tax savings alone. The exact ROI depends on property value, your tax bracket, and bonus depreciation eligibility.
By accelerating depreciation deductions, you reduce your taxable income in the early years of ownership. Lower taxes mean more after-tax cash available for reinvestment, debt paydown, or distributions.
Yes. The accelerated depreciation can create paper losses on the property that may offset other income, depending on your participation level and tax status.
Yes, if you qualify as a Real Estate Professional (REP) under IRS rules or meet material participation requirements for short-term rentals. In those cases, rental losses generated by cost segregation can directly reduce your W-2 taxable income.
REP status is an IRS designation for taxpayers who spend more than 750 hours per year and more than half their working time in real estate activities. It allows rental losses to be treated as non-passive, meaning they can offset W-2 or business income.
Depreciation recapture applies—previously claimed depreciation is taxed at up to 25% upon sale. However, the time-value benefit of having that cash working for you in the interim (plus potential 1031 exchange strategies) typically outweighs the recapture cost.
When you sell a property, the IRS requires you to pay tax (at up to 25%) on the depreciation you previously claimed. This applies whether you used cost segregation or standard depreciation—the depreciation is recaptured either way upon sale.
Typically: the closing/settlement statement, purchase price, depreciation schedule, and any available construction records or renovation invoices. If documentation is limited, we can work with cost estimation methodologies and public records.
Most studies are completed within 1–3 weeks from receiving your documents. Larger or more complex properties may take slightly longer, especially if a site visit is involved.
A detailed engineering report, asset classification schedule broken down by depreciation life, depreciation calculations, and CPA-ready documentation that integrates directly into your tax return.
Not always. Many studies are completed using construction documents, cost data, and virtual analysis. Site visits may be performed for larger or more complex assets to ensure maximum accuracy.
Our engineering-based studies follow IRS guidelines and industry standards. The methodology is designed for audit defensibility, and we stand behind our work.
No. Cost segregation is explicitly recognized by the IRS and has been upheld in Tax Court. Our engineering-based reports follow the IRS Audit Techniques Guide and are designed to withstand scrutiny if questions arise.
Pricing varies by property type, size, and complexity. We provide a fixed-fee quote upfront—no surprises. In most cases, first-year tax savings exceed the study cost by 5–10x or more.
Yes. We deliver CPA-ready documentation and are happy to work directly with your tax advisor to ensure seamless integration into your filing.
